[0028] The three different sensor data can be time-aligned, the intermediate data list has consistent data quantity after time alignment, the analysis result can be ensured to be unbiased when input into the analysis model, and thus an accurate analysis result can be obtained.

[0029] In another specific embodiment, the step of time-aligning the initial pressure data list, the initial temperature data list and the initial flow data list to obtain the intermediate pressure data list of the water pump device, the intermediate temperature data list of the water pump device and the intermediate flow data list of the water pump device further comprises the following steps: When K 0 , △T2 = min(△Y, △W, △L) is obtained; When △Y = △T2, the initial pressure data list is taken as the intermediate pressure data list, meanwhile, p initial temperatures with the smallest time stamp difference between the initial pressure data are selected from the initial temperature data list as intermediate temperatures to construct the intermediate temperature data list; meanwhile, p initial flows with the smallest time stamp difference between the initial pressure data are selected from the initial flow data list as intermediate flows to construct the intermediate flow data list; When △W = △T2, the initial temperature data list is taken as the intermediate temperature data list, meanwhile, q initial pressures with the smallest time stamp difference between the initial temperature data are selected from the initial pressure data list as intermediate pressures to construct the intermediate pressure data list; meanwhile, q initial flows with the smallest time stamp difference between the initial temperature data are selected from the initial flow data list as intermediate flows to construct the intermediate flow data list; When △L=△T2, the initial flow data list is taken as the intermediate flow data list, and at the same time, s initial temperatures with the smallest difference between the timestamps of the initial flow data are selected from the initial temperature data list as the intermediate temperature to construct the intermediate temperature data list; at the same time, s initial pressures with the smallest difference between the timestamps of the initial flow data are selected from the initial pressure data list as the intermediate pressure to construct the intermediate pressure data list. As can be seen from the above, the time alignment method can be simplified, and the working state data is constructed by selecting data with similar time, and the accuracy of the analysis result of the working state data is improved.

[0030] As can be seen from the above, the pressure and flow of the water pump are collected at a frequency of microseconds, and the temperature collection frequency has long-term stability, so the timestamps of the pressure, flow and temperature need to be kept consistent to avoid errors in the timestamps leading to inaccurate analysis results of the faults.

[0032] S302, when the fault analysis result of the water pump device does not meet the preset condition, a prompt information is sent; it is further understood that when F<F 0 , a prompt information is sent.

[0033] As can be seen from the above, by judging the mechanical state analysis result and the system state analysis result, the timing suitable for adjusting the operating parameter of the water pump device is determined, so that the water pump can maintain high efficiency under various load conditions.

[0038] Specifically, the pump shell and the impeller surface coating are nano coating, and the nano coating is prepared by resin sand precision casting process and nano coating spraying process, which improves the surface finish of the impeller, reduces the friction loss between the fluid and the impeller, and further improves the fluid conveying efficiency.

[0039] Further, the motor is used to drive the operation of the water pump device.

[0040] Preferably, the motor is a rare earth permanent magnet motor, which uses the strong magnetic field generated by the permanent magnet to drive the rotor to rotate, so that it can work normally without additional reactive excitation current; this not only greatly reduces energy loss problems such as copper loss and iron loss, but also ensures that the water pump can maintain a high efficiency operating state under various load conditions.

[0041] Further, the impeller has three blades and the three blades are spiral; which can reduce the flow separation phenomenon of the fluid on the working blade, thereby reducing the flow loss and improving the energy efficiency.

[0042] The above, by using the strong magnetic field generated by the permanent magnet to drive the rotor to rotate, so that it can work normally without additional reactive excitation current; this not only greatly reduces energy loss problems such as copper loss and iron loss, but also ensures that the water pump can maintain a high efficiency operating state under various load conditions.
